sharpening reflexes and technique

I know shadow boxing sharpens technique but does it sharpen reflexes also.

 

double end bag

 

Yea double end bag is fantastic for sharpening reflexes.I use to only use it when at the gym but I recently put one in the garage and My own reflexes have improve tenfold aswell as hand speed and co-ordination.Highly recommended.

 

Double end, speedbag, everything in boxing works reflexes at least a bit though.
